I Application 119d September 21, 1908. Serial No. 453,958.

To all whom it may concern:

Be it known that I, J ULws H. Sonnanr, a citizen of the United States, residing at Canton, in the county of Stark and State of 'Ohio, have invented a new and useful Culvert, of which the'following isa specifica- .comp etc pipe or culvert at the lace where the same is to be used, and the o ject of the improvement is torprovide a sectional nestab e culvert cheaply constructed, and convenient in handlin and erecting as well as strong and dare 1e. I attain these objects by the construction illustrated in the accompanying drawing, in which-- composed of nestab e half-sections embodying my invention, one half-section being fpartly removed to more fully disclose the construction. Fig.2 is a erspective view of a detached portion of t e spacing strip and flange plate used in constructing the offset flange. Fig.3 is a vertical transverse section throu h a culvert formed of halfsections embodying my invention.

Throughout the several views similar numerals of reference indicate similar parts.

The numeral 1 indicates a culvert halfsection which is preferably corrugated circumferentially although such corru ations are not essential to my invention. e entire culvert is composed of a number of such half-sections arranged preferably as top and bottom complementary half-sections, .the-

longitudinal scams or lines of union between said top and bottom half-sections lying referably in the same horizontal plane. Each half-section is provided with an ofiset flange, 2, consisting of a flan e late extending along the edge of said Eel? corru ated as in Fi 2 in order to follow the lines of the ha f-section if the corruated form of half-section is employed.

he spacing stri 3 consisting of a strip similar to the ange plate but narrower than said plate may be arranged between the edge of the half-section. and the said strip 2- for the urpose of spacing or offsetom the edge.

e strip anclplato are so arranged with.

-section and.

end edge of each half-section,'as shown at 6.

In the case of corrugated half-sections, as shown in the drawing herewith, this will permit the overlapping of the terminal corrugation of one half section over the terminal corrugation of the adjacent half-section, producing an engagement between corrugations adapted to lock the half-sections against relative displacement. An obvious Figure 1 is 0. pers ective view of a culvert While the drawing discloses half-sections,

each of which is provided along one ed e with an offset fian e producing a longitu ina] notch or socke the culvert might well be constructed with flanges on the two ed es;

of one half-section, the complementary ha fsection being wholly Without said flanges" without departing from the spirit of the present invention. The practical advantage of forming each half-section with one flange edge and one lain edge is that the half-sections will all e the some so that a culvert. may be constructed at any time out ofany number of said half-sections thus making it unnecessary to carry two different forms of half-sections in stock. It should also be stated that it is found practicable in some instances to form culverts of third-sections, instead of half-sections, and also of entire sections, thus necessitating but one scam.

I claim 1. A sheet metal culvert comprising longitudinally adjacent sections over-lapping at their meeting ends, each section having longitudinal scam edges and each section comprising means for uniting said longitudinal seam edges, and a portion of each section cut away to permit the over-lapping of the meeting ends of longitudinally adjacent sections.

2. A sectional sheet metal. culvert composed of complementary half-sections provided with circumferential corrugations, an offset corrugated flange plate secured to one seam edge of'each half-section, whereb to form a corru ted longitudinal slota on'g said edge, saiir plate terminating short of one end edge fon the purpose of permitting the lapping of terminal corrugations of Iongitudinally adjacent half-sections, and the said halfsections assembled with the unflanged edge of each half-section located within the longitudinal slot of its complementary half-section, and the terminal corrugations of longitudinally adjacent halfsections overlapping.

3. A seetiona s eet metal culvert composed of complementary half-sections, an ofiset flan e plate secured to one seam edge of each ha f-section, whereby to form a lon- 4 gitudinal slot along said edge, said plate terminating short of one end edge, for the purpose of permitting the overlapping of said end edge with the end edge/of a longitudinally adjacent half section, and the said hal -sections assembled with the unflanged edge of each half-section located Within the longitudinal. slo section, and'the end edges of longitudinally adjacent half-sections overlapping.

4. A sheet metal culvert composed of circumferentially corrugated complementar sections, each "section provided with an ofi set flange comprising a flange plate extending along the ed e 0 said section, said plate being corrugate to follow the corrugations in said sections and a spacing strip arranged between the said flange plate and the said section, the said plate, spacing strip and section formin a groove adapted to receive the ed e. o the com lementary section, means or fastening sai plate, strip and section together, said plate and strip terminating short of one end of said sectlon, whereby longitudinall adjacent sections may be over-lapped at t eir ends.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
